By definition, a colour sensor is a signal-emitting optical device that is used to selectively detect and evaluate the visible spectral range and is primarily used in the field of automation technology. Such sensors for colour detection should of course not be missing in our online shop for electronic components, which is why we present the corresponding products from this area here. These come, for example, from Adafruit, the renowned hardware manufacturer from New York City, which has been successfully represented on the market for more than 10 years.
